This Defense Intelligence Reference Document from the Defense Intelligence Agency is dated 23 March 2010. It was produced under the Advanced Aerospace Weapon System Applications (AAWSA) Program and surveys the history of attempts to use superconductors to manipulate gravity in the laboratory. It reviews theoretical work by Li and Torr, Podkletnov's disputed gravity shielding experiments, NASA replication attempts and Tajmar's results. It concludes that no repeatable effect has been verified and that research in this area remains fraught with experimental difficulty.

UNCLASSIFIED/ ;SF&lil: 8FFI1il.t.k Wfili &,.kY As of this writing, there have been no further pronouncements from Podkletnov. No one has published a replication of his "gravity beam" experiment, and as time passes, more and more scientists are coming to the conclusion that the experiment was never actually performed. Concerns about experimental procedures are not confined to the fringe, either. Final analysis of the Gravity Probe B satellite data is also apparently in serious difficulty (Reference 48), adding weight to the conclusion that experimentation in this area is fraught with difficulty even for the most experienced researchers. Conclusion Although the payoff of the discovery of a superconductor-mediated interaction between matter and gravity would be tremendous, only a few researchers are pursuing this goal. The main reason for this is the adherence to dogma concerning the impossibility of increasing the matter/electromagnetic coupling coefficients. This adherence is reinforced by reputable physicists pointing out that the theoretical constructs presented so far are based on questionable foundations. As with any forays into the unknown, one has to accept a few bumps along the way, including sometimes going back to the starting point in order to start again. The likelihood of scientific ridicule is extremely high in the search for laboratory-scale gravitational interactions. Increased understanding of the nature of high-temperature superconductivity will be advantageous in setting the firm basis from which to proceed. True scientists will continue to speculate about the ideas considered above, whether outlandish or not. Experiments will continue until either funding runs out or theory proves unequivocally that the expected effects will be far too small to see; however, experimentalists must ensure that other researchers have complete information so they can replicate experiments. Theory will continue regardless, but theoreticians must ensure that the scientific foundations are correct, and experimentalists must remain wary of potential traps. 1 Gravitational Wave Conference: International High-Frequency Gravitational Waves (HFGW) Working Group, The Mitre Corporation, McLean, VA, May 2003 2 Woods, R.C., "Gravitational Waves and Superconductivity," Space Technologies and Applications International Forum 2005, El Genk, M.S.
